Feature Changes
RCM HA switchover on mass UP failure is now supported in 5G-UPF.
Previous Behavior: RCM HA switchover occurs instantly when all UPs go down.
New Behavior: RCM HA switchover occurs after three minutes when all UPs go down.
Customer Impact: Reloading all UPs will not trigger RCM HA switchover in the usual RCM operation as the operator intentionally reloads all UPs.
Note | Undetected network isolation is not likely in this case as L2 VRRP protocol will cover any such network isolation case. |
